The reason why this isn't done is because the encoders required for
this are very expensive. Right now there are no consumer level
encoders that can encode an analog HD signal.
The people here are correct that capturing a digital stream would be
the ideal solution, with no reencoding the quality would be much
better. The proplem with this is that if all the cable companys
encrypt their content then capturing digitally might not be possible.
Either that or we could find some way to capture the encrypted stream
and get a decoder to play back that encrypted stream, but that would
suck for osd's and other such things.
